Sonardyne’s SPRINT-Nav 700 selected for new under-ice AUV

The UK’s center of excellence for oceanographic sciences, the National Oceanography Center (NOC), has selected high-performance hybrid navigation technology from Sonardyne International Ltd. for the next generation of its Autosub autonomous underwater vehicle (AUV), targeted for under-ice operations.The NOC, based in Southampton, will incorporate Sonardyne’s highest performing SPRINT-Nav inertial navigation system (INS) into the new 2,000 meter depth-rated Autosub, which is being specifically developed for carrying high-performance sensors on the most demanding research missions under

Researchers to Monitor Disruptive US Gulf Current

A major $2 million scientific study led by the University of Rhode Island (URI)’s Graduate School of Oceanography will monitor disruptive ocean currents in the US Gulf of Mexico, with a long term goal to improve forecasts for safer offshore operations in the region.The Loop Current System (LCS) is the dominant ocean circulation feature in the Gulf of Mexico, influencing all ocean processes in the Gulf with implications for a wide range of human and natural activities, from oil exploration to coastal eco-systems. To date, knowledge of its underlying dynamics is limited.URI’s initial study

submarine relief of this channel has been shaped by the action of several geological processes in polar margins. The gullies are the main topographic structures “that enabled the geological reconstruction of INBIS channel,” noted Leonardo Rui, member of the Trieste National Institute of Oceanography and Experimental Geophysics (OGS) and first author of the study.“In particular,” Rui continued, “the structure and some traits of these formations –for instance, ratio between dimensions and incision depth- help understanding the possible formation mechanisms and the differentia

ASL Hires Taillefer

ASL appointed Martin (Marty) Taillefer to the position of Senior Project Manager and Business Development. Taillefer has been working in the fields of oceanography, hydrography, ocean acoustics and underwater warfare for over 25 years. A naval officer for over 20 years, the latter 10 years were spent as an Underwater Warfare Director and Oceanographer for the Pacific Fleet. Taillefer oversaw the implementation and operations of decisional systems, acoustic modeling and operational systems to create operational products to the fleets. He also oversaw the routine creation and production of real-time

Scripps Adds New Research Vessel

The Scripps Institution of Oceanography at the University of California San Diego has added to its fleet a fourth research vessel, which was constructed by Armstrong Marine. The research vessel Bob and Betty Beyster is expected to launch in mid-April for use in San Diego.Armstrong Marine of Port Angeles, Washington, designed the 42-foot aluminum hulled boat. Pacific Power Group, working closely with Armstrong, fit the vessel with a Volvo Penta IPS 650 propulsion system. This is the first time PPG has mated the IPS configuration with an aluminum hulled boat.“We took a lot of time with the Scripps

to feed the world. People were building manned submersibles to go exploring in the deep. Aerospace companies were building submersibles, like Lockheed, North American, Rockwell and Westinghouse.”A lot had happened in the years before, recalls Kevin Hardy, who worked at Scripps Institution of Oceanography from 1972 to 2012, from the invention of pingers and even o-rings – a small component perhaps, but one that brought a break-though by improving seal reliability. The French invention and commercialization of the Aqua-Lung had provided scientists unprecedented access to their submerged subjects

Applications include autonomous underwater vehicles for propulsion, control, and instrumentation; in remotely located infrastructure equipment for valve control and pipe shearing; and in oceanography sensing set-ups such as those for monitoring the salinity and temperature of ocean water over a period of time.Compared to lead acid batteries, SeaSafe battery packs – weigh one-quarter, deliver longer mission times, provide up to four times more energy, and can take thousands of charges

a vehicle series known as the Odyssey Class. These were roughly 21 inches in diameter and about 2 meters long. They were designed to dive as deep as 6,000 meters but be relatively affordable and easy to deploy. These vehicles supported many science missions including under-ice work in the Arctic and oceanography in the Antarctic. A key program supported by these vehicles, sponsored by the Office of Naval Research (ONR), was known as the Autonomous Ocean Sampling Network. This pioneered designs for docking AUVs. Experiments in seafloor mapping and mine hunting were also conducted during the first ten years

Walter Munk: 1917-2019

Walter Munk, who gave the Allies a strategic edge in World War II, helped nurture a university into existence, and became a living synonym for oceanography, died February 8 at his home in La Jolla, Calif. He was 101.As a geophysicist at Scripps Institution of Oceanography at the University of California San Diego, Munk made groundbreaking observations of waves, ocean temperature, tidal energy in the deep ocean, ocean acoustics and the rotation of the earth. As an advocate of science and broader scholarship, Munk served as an advisor to presidents and the Pentagon and conferred with public figures

New Robot Can Sense Plankton Optically and Acoustically

A team of biological and physical oceanographers and engineers have modified a common physical oceanography instrument to be able to image zooplankton as it glides through the ocean.The robot, a first-of-its-kind sensing instrument dubbed Zooglider by Mark Ohman, a biological oceanographer at Scripps Institution of Oceanography at the University of California San Diego, uses as its platform a Scripps-developed glider known as Spray. Ohman and Scripps instrument developers outfitted the torpedo-shaped Spray gliders with a camera (called Zoocam) and a device researchers call Zonar that gathers acoustic
